[0029] When the staff needs to connect the furnace body 1 and the furnace cover 13, the staff needs to connect the furnace body 1 and the furnace cover 13 through the connection assembly 3. Subsequently, the staff needs to fix the furnace body 1 and the furnace cover 13 to each other through the bolts 15, nuts 16 and flanges 14, thereby reducing the probability of leakage when the device is used. In this process, the connection assembly 3 connects the furnace body 1 and the furnace cover 13 to each other, and the staff does not need to align the furnace body 1 and the furnace cover 13 when fixing them through the flanges 14, thereby reducing the difficulty of the staff's work.

[0030] The upper surface of the first connector 11 is provided with a plurality of limit grooves 2 in an array, and the inner walls of the plurality of limit grooves 2 are provided with a clamping groove 21. The connection assembly 3 is installed on the first connector 11 and the second connector 12, and the connection assembly 3 includes a limit block 31 and a clamping block 32.

[0033] When the limit block 31 slides into the limit groove 2, the circular block 4 slides into the circular groove 22. During this process, the circular block 4 limits the first connecting head 11, thereby reducing the probability of the first connecting head 11 and the second connecting head 12 being separated from each other when the staff fixes the first connecting head 11 and the second connecting head 12, thereby improving the stability of the device.

[0034] The gasket 5 is fixedly arranged on the upper surface of the first connector 11 , the circular block 4 penetrates the gasket 5 and is rotatably connected to the circular groove 22 , and the limiting block 31 penetrates the gasket 5 and is slidably connected to the limiting groove 2 .

Then, the staff slides the limit block 31 into the limit slot 2. At this time, the clamping block 32 is directly opposite to the clamping slot 21, and the clamping block 32 slides into the clamping slot 21 under the action of the return spring 6, thereby reducing the probability of the clamping block 32 blocking the limit block 31.

[0038] In order to reduce the difficulty of the staff's work, a first inclined surface 7 is provided on the edge where the upper surface of the clamping block 32 intersects with the side wall away from the reset spring 6. When the staff slides the limit block 31 upward, the first inclined surface 7 and the inner wall of the clamping groove 21 make the clamping block 32 slide into the groove 23, thereby reducing the difficulty of the staff sliding the limit block 31 upward, thereby reducing the difficulty of the staff's work.

[0039] In order to improve the stability of the device, a fixing ring 8 is fixedly provided on the bottom surface of the second connector 12, and the fixing ring 8 is tightly pressed against the gasket 5. The fixing ring 8 reduces the probability of the gasket 5 and the first connector 11 being separated from each other, thereby improving the stability of the device.
